PURPOSE:To feed wall material for transportation facilities, to be seen through, with optical characteristic from the viewpoint of an internal section, and optical characteristic from the viewpoint of an external section, different from each other. CONSTITUTION:Wall material for transportation facilities is formed with a transparent or semi-transparent substrate, a first colored layer 3, the concealed layer 4 of a white or light colored ink layer or the like having an adhesive force to the first colored layer, and a second colored layer 5 with designs, picture patterns, or the like displayed in screen, gravure, or offset printing. As a result, when the wall material is observed from a side (a) (the external side of a road, for example), the ink layers 4 and 5 can be observed. When the wall material is observed from a side (b) (the internal side of the road, vehicles on the road, and the like, for example), the ink layer 3 can be observed and is not influenced by the display pattern ink layers 4 and 5. |
